on the first question if you always want to set focus to FIRST element of
the FIRST form you can use:
<body onload="document.forms[0].elements[0].focus()">
on the second you can just loop over the elements array and grab what you
need

> I'm working on the checkout portion of a shopping cart app. First part

> document.form1.Firstname.focus();

> It's called at body onLoad and this works fine. However, I'd like to

> function toForm(theForm, theField) {
> document.theForm.theField.focus();
> }
>
> and then called it by:
>
> onLoad="toForm('form1','Firstname')

> However, I was getting errors stating that theForm and theField were

> Second question. I would also like to include the functionality to click
